what we collect, what we do with it, what we don't do.
LAST UPDATED · APRIL 2026
shimmer helps you see who else is at the bar, café, or restaurant you just walked into. That only works if we know where you are and who you are, so this document lays out exactly what we collect, what we do with it, and what we never do. Plain English wherever we can manage it.
shimmer ("we," "us") is operated by shimmer, Inc. You can reach a human at hello@shimmer.bar. For privacy-specific requests, use privacy@shimmer.bar.
Strictly to run the product:
We do not sell your data. We do not use it to serve ads. We do not share it with data brokers.
Only the infrastructure providers we need to operate:
We hand data to law enforcement only in response to a valid legal request (subpoena, warrant) or when we believe it's necessary to prevent serious harm. We'll fight overly broad requests.
You can at any time:
If you're in California, the EU, or the UK, you have additional rights (portability, restriction, objection, withdrawal of consent, lodging a complaint with a data protection authority). Email privacy@shimmer.bar to exercise any of them.
All data is transmitted over HTTPS. Authentication and storage sit on Google Firebase infrastructure with industry-standard access controls. Nothing is unhackable, but we treat your data like we'd want ours treated. If there's a breach that affects you, we'll tell you within 72 hours of discovery.
shimmer is for adults. You must be 18 or older to use it. We don't knowingly collect data from anyone under 18. If we learn we have, we delete it immediately. If you believe a minor is using shimmer, email abuse@shimmer.bar.
We use browser local storage to keep you signed in between sessions. We don't use third-party advertising cookies. We don't track you across other sites.
shimmer is a U.S.-based service. Your data is processed and stored in the United States on Google Cloud infrastructure. If you're outside the U.S., using shimmer means your data moves across borders to get to us. For EU/UK users, that transfer happens under Standard Contractual Clauses.
If we change how we handle your data in a way that affects you, we'll tell you in the app before the change takes effect. For minor edits (typos, clarifications), we'll update the date at the top and keep going.
If you live in California, you have the right under the CCPA to know what personal information we collect and how we use it (covered above), to request deletion (Settings → Delete account, or email us), and to not be discriminated against for exercising those rights. We don't sell or share personal information as those terms are defined under the CCPA.
